Prosthetic Knee & Above Knee Prosthetics
At Amputee Clinic in Fort Myers, we provide advanced prosthetic knee solutions designed to restore safe movement, stability and confidence for above-knee amputees. A prosthetic knee plays a central role in how you walk, sit, stand and navigate daily life. Choosing the right knee system requires clinical expertise, careful evaluation and ongoing support.
Our team combines more than 100 years of clinical experience with an on-site lab and advanced physical therapy to deliver prosthetic knee care that is precise, practical and tailored to real-world needs. From first consultation through long-term follow-up, our focus stays on outcomes that improve mobility and independence for our patients.
How Does a Prosthetic Knee Work?
How Does a Prosthetic Knee Work?
A prosthetic knee replaces the function of the natural knee joint after an above-knee amputation. It controls how the leg bends and straightens during walking, standing and sitting. A well-fitted prosthetic knee helps reduce falls, improves gait symmetry and lowers strain on the hips and lower back.
Every patient presents different goals, activity levels and physical considerations. That is why prosthetic knee options are never one size fits all. At our Fort Myers clinic, we evaluate strength, balance, walking speed, terrain demands and lifestyle needs before recommending a specific prosthetic knee type.
Who Is This For?
This service is designed for above-knee amputees who want a prosthetic knee that feels stable, comfortable, and suited to real-life demands. It supports people who are newly amputated, returning to mobility after surgery, or struggling with balance, fit, or confidence in their current prosthesis. Our care suits both lower and higher activity levels, with each prosthetic knee selected to match physical ability, daily routines, and long-term mobility goals.
Prosthetic Knee Types Explained
Modern prosthetic knee types range from mechanically simple designs to highly responsive computerized systems. Understanding these options helps patients make informed decisions in partnership with their care team.
Single-Axis
Knee Prosthesis
A single-axis knee prosthesis features a simple hinge mechanism that allows the knee to bend and straighten on one fixed axis. This design offers predictable motion and durability. It often suits individuals who prioritize stability and straightforward function.
Single-axis knees can work well for users with consistent walking patterns and lower activity demands. They are also easier to maintain and adjust, which can be beneficial during early rehabilitation.
Polycentric
Knee Prosthesis
A polycentric knee prosthesis uses multiple pivot points to mimic the natural movement of the knee more closely. This design shortens the leg during the swing phase, improving toe clearance and reducing the risk of tripping.
Polycentric systems often provide enhanced stability at heel strike and during standing. Many patients appreciate the smoother motion and added security, particularly when navigating uneven surfaces or slopes.
Weight-Activated
Stance Control Knee
A weight-activated stance control knee increases resistance when weight is placed on the prosthesis. This added resistance helps prevent unwanted knee buckling during standing and walking.
This type of prosthetic knee supports users who benefit from extra stability while still allowing controlled knee flexion during swing. It can be an effective option for individuals rebuilding strength and confidence after amputation.
Manual Locking
Knee Prosthesis
A manual locking knee prosthesis allows the knee to be locked in full extension. When locked, the knee does not bend, providing maximum stability during standing and walking.
While this limits natural knee motion, it can be appropriate for users with significant balance challenges or those who prioritize safety over flexibility. The lock can be released for sitting when needed.
Microprocessor
Knee Prosthesis
A microprocessor knee prosthesis uses sensors and onboard processing to adjust resistance in real time. These systems respond to walking speed, terrain changes and movement patterns.
Microprocessor knees often provide smoother gait transitions, reduced fall risk and improved energy efficiency. For many active users, this technology supports more natural walking and greater adaptability in daily life.
How We Select the Right Prosthetic Knee
Selecting a prosthetic knee involves more than matching a device to an amputation level. Our clinicians take time to understand each patient’s goals, physical condition and daily routines.
The evaluation process includes gait analysis, strength testing and discussion of environmental demands such as stairs, ramps and uneven ground. We also consider long-term health factors like joint protection and energy expenditure.
Because we have an on-site lab in Fort Myers, adjustments and refinements happen efficiently. This allows faster optimization of fit and function without delays or outsourcing.
Integrated Care for Better Outcomes
A prosthetic knee performs best when paired with comprehensive rehabilitation. At Amputee Clinic, advanced physical therapy supports strength development, balance training and gait refinement.
We also offer same-day sockets when appropriate, reducing downtime and improving comfort during transitions. Education on prosthetic use, skin care and maintenance helps patients stay active and avoid complications.
Our multidisciplinary approach ensures that the prosthetic knee works in harmony with the rest of the prosthesis and the body.

Frequently Asked Questions
How much does a prosthetic knee cost?
Prosthetic knee cost is typically covered through Medicare, Medicaid, or insurance plans for eligible patients. Coverage depends on medical necessity and functional classification. Our clinic manages insurance billing and documentation to reduce stress for patients.
What is the lifespan of a prosthetic knee?
The lifespan of a prosthetic knee depends on the type, usage level and maintenance. Many knees last several years with proper care and periodic servicing. Regular follow-up helps identify wear early and maintain performance.
Do prosthetic knees require maintenance?
Yes, prosthetic knees need regular checkups to ensure proper alignment, resistance settings and overall function. Routine maintenance helps prevent discomfort and reduces fall risk. With our on-site lab in Fort Myers, adjustments happen quickly and efficiently.
